Lithium battery
The P5000HX CPU Card contains a built-in, high-capacity
lithium battery that retains the correct time, date and
computer parameters in CMOS memory when the system
is powered OFF. This retained information assists BIOS in
performing initialization and configuration during power-
up or reset operations. The battery is designed to provide
years of service without replacement. However, if configu-
ration or clock-related inconsistencies occur, the battery
may require replacement. Please return the P5000HX
to the factory for battery replacement.
